Specification of Letters Patent.

Patented-Jinan, 1913.

Application filed au ust 26, 1912. serial no. 717,151.

To all whom it may concern Be it known that I, WILLIS GRANT MUR- RAY, a citizen of the United States, resid ing in the city and county of San Francisco, a State of California, have invented certain new and useful lmprovements in Vacuum Syruping-Machines, of which the following is a specification.

My invention relates to vacuum syruping machines, and its object is to provide .a rapid and efficient means for syruping cans by the vacuum process, and to automatically receive, syrup and discharge the same in a safe and satisfactory mannen- For a clear comprehension of the invention reference should be made to the drawings accompanying this specification in which Figure 1, isa plan view of themachine showing the syruping mechanism, adjusting screws, opening and closing trips for the valves and the pipe, connection to the liquid reservoir, the open section disclosing a vacuum connection, the carrier head, and the receiving and discharging gears with broken sections of the table along which the cans are delivered to the machine and discharged therefrom. Fig. 2, is a front elevation of the machine showing the carrier head with the cans in place, the double reservoir with pipe connections, two-way valves with star control, Opening and closing trips With cut-out for an empty section, the arrangement of the gears and sprockets for the receiving and delivering mechanism, the adjusting screws, a means or applying the power to operate the machine and the clutch control. Fig. 3, is a sectional view in elevation showing the double reservoir, the syrup- 'ing pipe above and the vacuum ipe connection through the hollow shaft rom below;

,the two-way valves with star control and the pipe connectionto the double reservoir, the ear connected double adjusting screws for t e elevation or depression of the syrupin head, the ball bearin between the revo ving mechanism and t e base, the automatiio ifting plungers and the means for applyingl the power to operate and control the mac ine. Fig. 1, is an enlarged detail view of the opening and closin trip with cut-out or empty section in its re ative position to the star controlled two-way valve. Fig. 5, is a front end viewin elevation of M the star controlled two-way valve. Fig. 6,

is asectional view of the two-way valve open to the vacuum pipe line. Fig.7, is a sectional view .of the two-way'valve open to the syrup pipe line. Fig. 8, IS a view of the two-way valvein cross-section after the star 0 head has passed the closing trip. Fig.- 9, is a sectional view of the star controlled twoway valveafter ithas passed the placing trlp and is now in position to be opened to the vacuum pipe line.

The numeral 1, is2used todesignate a stand or base on which. the mechanism is assembled. i.

2, is the syruping'head with the double reservoir whose upper chamber 3, isthe receiving tank, and the lower 4, is a means through which the suction is applied to produce "the vacuum, in the can prior to syruping the same. Radiating from the. chamber 3, are the distributing pipes 5, 5, while from the chamber 4, the suction pipes lead, both ending in suitable connections to the star controlled two-way valves 7,7.

The numerals 8, 8, indicate the star heads controlling said valves.

9, is the carrier head with the flange 10, rigidly secured thereto, said'flange having the depressions 1 1 11, of suitable depth and shape to receive the cans and hold the same in position for syruping and delivery.

12,.12, are the plungers of the carrier head designed to bring the can into airtight contact with the openings 13, 13, of the two-way valves 7, 7. To insurean airtight connection with said openings the elastic cap 14, is provided.

15, 15, are the hearings or pockets in which the plungers 12, 12, are slidably mounted; rotatably secured in the lower end of said plungers are the small wheels or rollers 16, 16, so disposed as to engage and roll upon the tracker rail 17. This track or rail isof difl'erential height thereby causing the plungers to rise or fall at the proper time to receive the can, form the air-tight joint with the two-way valve, release and allow the same to be discharged as the carrier head with its assembled mechanism revolves. I I

18, 18, are the gear connected adjusting screws for raisin or lowering the syruping head to suit the eight of thecan used.

19, is the driving sleeve to which the carrier head 9, is secured; while 19 is the ball bearing. between the'revolving mechanism and the base. The driving sleeve 19, passes through the central bearing 20, and secured to the lower end thereof is the main driving gear 21. The power is applied to said gear by means of the pinion 22,"rigidly secured a to the shaft 23, on the outer end of which the belt wheel 24, with the controlling shaft passing through the bearing thus formed enters the chamber 29, to which is' suitably attached the vacuum pipe line 30. On the outer end of the webbed member 25,

,clutch 24' is mounted. In the lower part of the base the webbed section 25, is secured, in the center of which is the pocket 26. Entering this pocket through the stufing box 27 is the upright hollow shaft 28; said the bearing 31, is secured, the said bearing having movably mounted therein the shaft 23, with its pinion 22, andthe belt wheel 24, with the clutch control 24". In the bottom of the pocket 26, is aclean-out valve 32, for convenience in removing any accumulation of oil or sediment from the chamber 29.

' The upri ht hollow shaft 28, extends from the cham er 29, through the driving sleeve 19, and ends with a taper fit in the syruping head 2; the said shaft is secured therein "by the flanged cap screw 33, which forms an air-tight joint closin the upper end of the upright hollow sha 28.

Arranged on either side of the flanged -cap screw 33, are the twin pipe connections 34, 34:, entering the upper chamber .3, of the double reservoir. The center upright mem-- ber of the twin connections indicated'by the numeral 35,.is oined to the supply pipe 37,

. by the rotatable union 36.

Rotatably mounted on the upright holflow shaft 28, between'the carrier head 9, and

the syruping head 2, is-the gear 38, connectin the adfiistin screws 18, 18,-by' means i of the inions 3 ,39. Mounted on one of the ad usting screws and rigidly secured thereto is the hand wheel 40, which provides a means for operating the same.

: Rigidly secured 'to the driving sleeve 19,

' and below the bearing 20,, is the gear 41,

i driving the pinion 42, and the shaft43., On the.sha'ft 43,, the. sprocket 44, is secured; said sprocket being the means, (through a triangular chain connectiomgl for driving the 7 loading gear 45, and the disc -Attached to the shaft of the loading gear [.45, is the bevel gear 47 the said bevel gear by means of, the bevel pinion and shaft 48,;

= drives the sprocket49I The sprocket 4:9, in

P so:

turn becomes the'mansofibperating the endless carrier chain 50; the said chain -passes under the idler'sprocket 51,. and. over-- the idler sprocket 52, thusmakin it possl iblej to use the same chain to disc arge thegame e-load 'the'.machine. At the um- .ends of table are installed other'idler sprock-' Jets lover. which the endless carrier chain fat passes that it mayreturn under the table;

arging gear. 46.

I ma am the said sprockets are not shown in the drawings.

Mounted on the. base and rigidly secured thereto are the pockets for the adjustable pillars 53,54, 55, 56. The said pillars are arranged on either side of the revolving head of the machine in a suitable position for the purpose required. 'At the top of said pillars and at right, angles to the same, the slotted bearings 57 and 58, are mounted; the same being a suitable distance apart to provide'for the operation of the rocker arm. Slidably mounted in the bearing 57, is the spring plunger 58., having in the side there-v of the pin 59, operating in the slot 60, Movably mounted in the bearing 58, is the sliding member 61, having on 1ts inner end the arcuated' head 62 and in theside thereof the pin 63, operating in the slot 64.

By means of the rocker arm 65, oscillat- 'ing on the central bearing 66, with its elongated holes 67, 67, engaging the pins 59, and 63, an alternating movement is imparted to the spring plunger 58, and the sliding member 61, that is utilized in the following manner: Asthe' can D, (carried by means of the depression 11, in the flange of the carrier head 9,) passes the arcuatedhead 62, of the sliding. member 61, it forces the said member "ing the .same one quarter turn. This movement taking place at the first pillar 53, opens the two-way valve to the vacuum pipe line. The same operation is repeated at the second pillar 54:, at which point the valve closes the vacuum pipe line and opens the syruping pipe line, the same remaining openuntil the carrier head has made ap roximately one half turn. At the pillar 55, t e movement of the parts described is repeated, the valve now closing the syruping pipe line. At the pillar 56, the repeated'moveme'nt of the mechanism places the valve in position to be opened for the vacuum at the pillar 53. Should one or more of the spaces in the carrier head be 'empty, the said space passes the arcuated head of, the sliding member 61,. at all the stations thereof without operating the valve. As the cans are passed into the carrier head by the loading gear45, the-plunger 12, raises them into air-tight contact with the elastic ca "14, by means of the incline 69, on the di erent-ial'rail 17. I The rail maintains them in this position until they closing mechanism at the pillar 55. Q

have passed the Y The powerto eperate the machine as w'ell (as, the suction. required to produce the vacu-, um may be supplied in the ordinary manner.

The advantages of the device are apparut a small opening to be operated on by my ma ent. The can to be syruped requires chine, this insures quick and easy sealing while the extraction of the air from the can leaves it in a condition to-receive the liquid. As to the ra idity of operation it can be readily seen t at the ceaseless moving of the cans through the machine and their discharge therefrom can only be productive of the highest eficiency.

I do not wishto be understood as confining myself to the precise construction shown herein, but wish to avail myself of any modifications that may fall properly within the scope of my invention.

Having thus described my invention, what I claim as'new and desire to secure by Letters Patent, is

In combination, a rotating syruping head with a double reservoir-,comprismg an upper syrup chamber and a lower vacuum chamber, a syrup supply source, a vacuum creating source, a fill ng head provided with a two-way valve, pipe connections leading from said syrup chamber to said syrup supply source, a hollow shaft communicating with said vacuum chamber of the reservoir at its upper end and at its lower end communicatmg with said vacuum creating source, separate pipe connections between the syrup and vacuum reservoir chambers and said two way valve of the filling head, and means automatically operated by the rotation of the syruping head for controlling said two way valve comprising a star head carried by the valve, an arm for actuating said head held normally pressed outward, a second arm positively operated by the can. a lever between the arms'to communicate the movement of the lower arm to the upper and force the upper inward, the said lower arm having means projecting into the path of the cans, to be actuated thereby when a can is in osition on its supporting head,
